$bomb=array(
'<',
'>',
);
$defusal=array(
'-',
'!',

$string= preg_replace($bomb,$defusal,$string);
echo $string;
?>

error:
Warning: preg_replace() [function.preg-replace]: No ending matching delimiter '>' found in C:\xampp1\htdocs\code.php on line 13

donno any further now

does anyone know how to decode this XML variable value into string values? I also need to know the oposite way: creating variable values into xml. I've tried several code examples but they did filter the requested data.

Code: [Select]
$xml='<?xml version="1.0" encoding="utf-8"?>

Ok mixing javascript with php.... im having bugs .

I basically want to replace any broken image links with a picture "noimage.gif" in the images folder.

I tried this code but am getting the error:
Parse error: syntax error, unexpected T_STRING, expecting ',' or ';' in /home/wormste1/public_html/tilburywebdesign/shop/FTPServers/barryottley/showroom.php on line 78

This is the javascript header - all seems fine:
<script language="JavaScript" type="text/javascript">

function ImgError(source){ 
    source.src = "/images/noimage.gif"; 
    source.onerror = ""; 
    return true; 
} 


</script>

this is the code thats erroring... is it the way ive written in the code into the IMG tag?

while($row = mysql_fetch_array($result)){
echo "<TABLE CELLPADDING=0 CELLSPACING=0 WIDTH=100% BORDER=0>";
echo "<TR />";
echo "<TD WIDTH=30% VALIGN=TOP />";
echo " <A HREF='images/".$row['photo']."' target=_blank><IMG SRC='images/".$row['photo']."' width=186 height=155 border=0 onerror="ImgError(this);" /></A> ";
echo "<br />";
echo "</TD>";
echo "<TD WIDTH=10 VALIGN=TOP />";

Hi Guys,

I use this function to generate seo friendly names for my products once pulled from the database:


function generate_seo_friendly_links($pNM, $pID)
{
    $replacedNM = str_replace(" ", "-", $pNM);  
    $replacedNM = rtrim($replacedNM);  
    $brandNewSEOFriendlyURL = "<a href='$replacedNM-$pID.html'>$pNM</a>";    
    return $brandNewSEOFriendlyURL;
}


This works great, the only thing is say a product is stored in the database like:

product name it would then be converted to: product-name.html

if for example theres 2 spaces:

product  name it would then be converted to: product--name.html

with the 2 "--" so for every space it finds we replace with a "-" etc

is there a way i could ignore more than 1 space and always have it like product-name-here.html so the names are more uniformed, i can't think of a way to do it.

any help would be appreciated

thanks guys

I have phrases in a string with the structure of "Note: some description" I want to replace "Note with (, but how can I replace the second " with )?

I'm having an issue with users uploading files with a Semi Colon in the file name.
I am currently using a script that replaces characters within the file name, however, when I try to add a ";" as invalid characters to replace, it is like the semi-colon just stops the script, as the file does not upload (no errors are displayed).

Here's the code I'm working with:


$valid_chars_regex = '.A-Z0-9_ !@#$%^&()+={}\[\],~`-';
$file_name = preg_replace('/[^'.$valid_chars_regex.']|\'.+$/i', "", basename($_FILES[$upload_name]['name']));
if (strlen($file_name) == 0 || strlen($file_name) > $MAX_FILENAME_LENGTH) {
HandleError("Invalid file name");
exit(0);
}


I tried placing the semi colon all over the place in the preg_replace function, but nothing seems to work.

How can I do this?

Hello,

I have been trying to replace a variable's value inside a function in case it matches a certain criteria but I can't seem to get it right.

Let me give an example:

Code: [Select]
<?php

function replace_value($obj)
{
if($obj==1)
{
$obj=2;
}
}

$number = 1;
replace_value($number);

echo $number;
So how do I go about making $number = 2, because it still has a value of 1 even after I pas it through the function replace_value.

How can I replace ' and " with str_replace? When I using the following code, I will get error.
$string = str_replace(""", "something", $string);

//$x = ereg_replace('[-a-z0-9!#$%&\'*+/=?^_`{|}~]+@([.]?[a-zA-Z0-9_/-])*','<a href=\'mailto:\\0\' '.$style.'>\\0</a>',$x);

If this were an example post in a forum:
Code: [Select]
$post = '[quote author=james]hello this is a quote[/quote]

here is some mor text between the next coming quote

[quote author=david]hello this is another quote[/quote]';
What is the best way to replace the [quotes author=x] with opening html tag
eg:
Code: [Select]
<div class="quote"><div class="quoteTitle">author=x</div>
And then determine if the next is a [/quote ] is an opener or close quote?

And then of course there is the  issue of the user deleting a [/quote] or even placing a [/quote] before an open quote...

Does anyone know of an example to look at?

Hi

I wonder if anyone will be kind enough to help.

I am getting into forking with pcntl_fork()

I intend to create a script that runs 24/7 running 100 forks/children/'threads' simultaneously.

Once a child has finished it's task and exited how can I start a new child to replace it?

I need some kind of infinite loop that can continually check for exited children and set up new ones.  I'm finding it hard to get my head round since I'm new to forking.  Can anyone suggest a way to do this?

Thanks in advance.

Hi first post here and very new to php. I built a form so that a data entry perosn can "build" new pages for our companies website. I pretty much have the basics of the form and the action page coded correctly, however my issue is that I need this final page where the form inputs are posted too to be an html document.

I read some about the str_replace() function, but I'm not understanding how I could use that to replace the file extension of a page.

Maybe I'm going about this all wrong. I also read that one can edit the htaccess folder to allow an html file to run php script. Not sure which way would be the best. One thing to mention though, is this application would be run locally to our back up files which is then scheduled to be uploaded to the remote server very night.

Any help or suggestions would be greatly appreciated.

I want to be able to replace, let's say, every fifth letter from a string.

The string is unknown, though, it could come from database, or a POST form. So I'm unsure if I could use str_replace.

I think I may need to use preg_replace(), but I'm not not sure.
